Supports IDE hard drives and SATA 2.5 "and 3.5" external power supply.
PC USB2 connections with only the front but fortunately a port eSATA II. I had until now 2 IDE HDD external USB2-connected and grieved me not to take advantage of the speed of eSATA.
That's why I chose this dock eSata / USB2
As fast as internal hard disk HDD Sata! (With Sata hard drive, of course)
Under CrystalDiskMark, sequentially, just 5 times faster than USB2!
Only problem: the Dock accepts a SATA hard drive + IDE. But according to the instructions in this case, both are accessible only via USB. If one connects to the PC via USB and eSata, only IDE hard drive is accessible. And if eSata connection, one also Ide. I have not tested.
Ideal for recycling old hard disks.
